CathFlow® antifouling system (MGPS/ICAF)
CathFlow® electrolytic antifouling supresses corrosion and prevents mussels, barnacles and similar organisms from establishing in seawater systems.
The CathFlow® system works by releasing antifoulants (ions) in the seawater, forming an environment that mitigates corrosion and discourages organisms to adhere, grow and start breeding.
MasterCath® – remote access software
MasterCath® works by pairing a remote computer with CathFlow® control panels for MGPS/ICAF antifouling systems onboard the vessel.
The software provides an intuitive dashboard with real time operational values, alarm detection and several other useful features.
CathSense® ICCP systems for underwater hull protection can also be accessed through MasterCath®. Learn more about MasterCath® remote access sofware.
MGPS/ICAF antifouling explained
Marine growth preventions systems (MGPS) and impressed current anti-fouling (ICAF) are based on producing copper ions in very small concentrations, which is enough to prevent or reduce the ability of marine organisms (mussel and barnacle larvae) to settle and breed.
Instead of adhering to the surface of seachests, strainers, piping or box cooler tubes the mussles and larvae pass harmlessly through the cooling water system to the point of discharge. Learn more about the prinicples of electrolytic antifouling.

Copper rod anodes are well arranged underneat the box cooler to provide even distribution of antifoulants. The release of copper ions will create an environment that discourages marine growth at the box cooler and in the sea chests.
If the MGPS/ICAF system is properly designed and operated, the copper anodes will also provide cathodic protection of the sea chest.

Seawater inlet with flange anodes
Copper and aluminium/iron anodes in pair are installed in the sea chests to treat the seawater before entering the seawater piping. As the antifouling effect gradually decreases inwardly the piping system, complementary anodes may be required in the cross-over tanks or in mud boxes for larger seawater systems.
Anodes underneath seawater inlet
In some cases it is recommended to install MGPS/ICAF anodes directly underneath the seawater inlet to ensure the antifoulants enter the pipings.
Anodes in mud box
Anodes can be mounted in strainer lids as shown in illustration below. This arrangement will treat the water against fouling in mud boxes and further upstream. You may also want to read about antifouling anodes in strainers.
